The train smelled awful when I was riding a mixture of food and piss aka pee-pee mixed with sodium intestinal smell … pee mixed with drugs… n then my eyeballs r shot open from riding the train. These masks 😷 that Covid19 made me wear…. doesn’t filter out what I want it to filter out … cigarette smoke. I want it to filter out cigarette smoke. I’m having to add extra layer of cloth to the mask I’m wearing… protecting myself from cross contamination of air being caused by an irresponsible cigarette smoker…
